Revision as of 05:28, 23 December 2011

The Allwinner A1x family has three chips, A10 A12 and A13. A12 and A13 are the cost-down version of A10.

A10

The Allwinner A10 CPU has been developed in, and is sold in, the People's Republic of China. Its mass-volume price is around $7, yet it is a 400-pin highly feature-rich 1.5ghz ARM Cortex A8 with a MALI400 GPU. It has the distinction of having the highest bang-per-buck ratio of any SoC available at the time of writing, by quite a margin. Its price and features is causing massive disruption of the tablet market in China (a minor recession was caused by widespread cancellation of prior committments to other SoCs!), as every factory in Shenzen scrambles to compete with hundreds of other factories for the same end-user market: tablets(see A10_tablets) and PVRs.

For comparison: TI has brought out a new $5 ARM Cortex A8, but it is limited to 500mhz and it is extra cost for the version with a PowerVR 3D GPU. Ingenic's jz4770 is about $7 in mass-volume but it is a 1ghz MIPS with a Vivante GC600 3D GPU. Details are harder to get hold of regarding the jz4770, but its interfaces are known not as feature-rich as the Allwinner (no HDMI output for example). AMLogic's Cortex A9 is $13 in mass-volume, but is limited to 800mhz and a maximum of 512mb of RAM.

Unsurprisingly, this CPU has been chosen as the first CPU for an Embedded_Open_Modular_Architecture/PCMCIA CPU module by Rhombus Tech. The critical decisive factor however was the immediate support of Allwinner's Board of Directors for releasing full GPL Source Code, to help the RHT Initiative to foster better relations and closer ties with Free Software Developers.
